Training ground in Hideouts

Add a new training ground

You can call out any kind of monster

You can set the level of the monster

Monster Died without experience points and items

Hit the monster will show the figures

If you are attacked by a monster
Will show damage figures

You can call out every 1 to 5 monster at one time

Once again call out the monsters need to destroy all monster

If you die will not reduce the experience

I was thinking about this also.
My idea was to have a statue (or more) in hideout, that could be activated (and with changeable stats - like HP, damage, resist etc) and fight to train or test skills. When statue or the player is on 1 HP, it will return to the stand and wait.
But it would require new room. We could build an arena and masters could have different combat statues. With microtransactions to change their appearance :D
